Not a solution to the site problem, but to recovering posts using Firefox. Install the Lazarus add-on, and specify as much time to save your entries as you wish. The default is 14 minutes, but I have it set for several years. (!!) Allows me to revisit posts I made long ago, if a subject recurs.
Operates with a button on the Addon bar and in the context menu. (“Recover text”)
Don’t leave home without it!
A complementary tool, btw, is ClipMate, a $35 stand-alone product that saves anything you copy, for as long as you want. Most useful utility evah.
